IMPROVEMENT dated November 29, 1870.-

m HvoRANTs.

The Schedule reien'ed to inithese Letters Patent and making part of the same.

I, ELIAS Gnnnrrr'r, of the city of Baltimore, in the State of Maryland, have invented au Improved H ydrant, of which the followingr is a specification.

Nature and Objects of thc Intention.

The hydrant is onein wllich, when the discharge is stopped, thewater in the discharge-pipe sinks into a chamber below the level of frost.

This chamber is, by preference, a' hollow sphere of India rubber, which dilates to receive the water sinking from the discharge-pipe, and which is compressed tor discharge its contents when the outward l'low is resumed.

The bulb is not, for any length of time, in direct connection with the main.-

\Vhen the discharge-pipe is depressed, the waterconnection is accomplished and discharge takes place.

`iVhen`the pipe is raised, the water-connection with ceives the subsiding -water from the discharge-pipe.

'lbe elevation of the discharge-pipe is performed by a spring, which also acts as apacking in the duct bctween the main and the bulb.

'lbe handle is hinged to astud without the intervention of screws or nuts.

The nozzle is a bcnttube, which screws into an cl bow on the discharge-pipe; a stud and rose on the nozzle-pipe, and a plate attached to the face of the box, keep the nozzle at a proper extent of protrusion.

A yoke forms a guide for the discharge-pipe, and at its lower portion forms a part ot' the clamp which holds the elastic reservoir in position.

Description of thc Accompanying Drawing.

Figure l is a side elm-ation, one side of thc hydrantbox being removed.

Figure 2 is a front elevation of the upper part of the box, showing the handle.

Figure 3 is a section, on an enlarged scale, showing the construction ot' the parts iuurlediatelyconcerned in the opening and closing of the water-commotion.

General Description.

dlc is raised and the main connection severed.

Gis the Vdischarge-pipe,.which has au elbow, H, and a nozzle I.

On the latter are astud, a, and a rose or boss, K, which are on the respective sides of the plate b, to keep the nozzle from slipping out or in beyond the assigned limits. y

' The handle J has a long slot at the point where it incloses the pipe I, and another opening where it is hinged tothe stud M. 'Ihe latter has a projecting lugfwhich only allows-the handle to be attached when thc latter is raised vertically; being then brought into the-position shown in lig. 2, the lug prevents the handle from slipping oti, and thus a cheap, convenient, and effective .connection is obtained without a screw and nut, the usual mode vof attachment.

The handle being in the position shown ,in g. 2, the nozzle I is to be inserted through the slot, and then screwed into the elbow H.

The stud is passed through the opening in the plate b,`wheu the nozzlcis turned sidewisc, and the latter being then turned spout down, the stud catches behind the plate b and prevents the spout from being pulled out, while the. boss K keeps it from being pushed in. v

rIhe depression ol' the pipe G causes the discharge ofthe wat-er, as will be presently explained, and the lifting of the pipe stops the flow. p

When the handle is depressed, it may be caught beneath a notched plate, and the dow is thus made i continuous without the trouble of holding it.

11 is a hollow sphere of India rubber or other ilexihle material, having openings in the top and bottom. The edges ofthe upper orifice are clamped between a cup-shaped disk, I., and an enlargement, N, on the foot of pipe G.

lIhis elastic bulb sits iii a cup, E, which preserves its form to some extent when compressed, as shown in lig. 3.

The edge of the lower-orifice in the bulb is clamped in a groove around the upper portion of the box D by the rising of the collar l, on which are erected the yoke It and guiding-sleeve 8, through which the pipel G slips as the handle .I is raised and lowered.

'l1 is a short pipe, which is open atA its upper end,

the pipe 'I and closes the openings in the lower end of said pi pe.

The raising ofpipe Grestores the bulb F to its full capacity, and the water subsiding in the pipe G Ills the bulb, which is placed below the access of frost.

When the handle is again depressed, the contents of the bulb are driven up the pipe Gr, which then comes in contact with the top of the pipe T, and, by

depressing it, causes the water of the main to ilow through the connected pipes T G to the nozzle.

o. The hydrant-nozzle I, scoured in the frame or casing by the stud a andv plate b, aud screwed into the elbow of the delivery-pipe, all substantially as described.

4. 1n combination with the nozzle I, and as a means of operating,` the saine, the handle J, slotted as represented, and secured to the frame or casing by means of the stud M, as described.

5. The yoke l) 1t S, combined with the deliverypipe G and reservoir F, as described.

6. The handle J, pivotcd, as set forth, with an ob'- long.,r slot, in combination with the nozzle and pipe, and a valve operated by a downward pressure dcrived from said handle, substantially as described.
